In Italy June 18, ms 1 Claim.'. (Ci. low-is) The object of the presentinventionis to ob-- tafn, by means of a very simple machine, a perfect continuous and automatic kneading of a mixture of coarse and fine flour and water, fed in a continuous and automatic manner to said machine.

a Perfect kneading" means" that" the mixture of proper die, of conventional design; which die is supported .by ring at.

The operation of the machine is as follows: The mixture of coarse flour, fine flour and waterfed from hopper it is prepared in a usual mixer with intermittent or continuous production; the mixture is caught by't'he Archimedean screw and thoroughly kneaded into an homogeneous The machinain fact, achieves in a continuous manner the fundamental operation of usual kneading. machines for macaroni, nainelypartial'shifts of paste in the dough, with immediate mutual compenetration of the parts of'the paste itself.

The accompanying drawing illustrates, simply by wayof example, an embodiment of .the machine, according to vthe present invention.

The drawing shows in Fig. l a partial longitudinal section of the machine, Figs. 2 and 3 showing two details thereof.

Referring more particularly to the drawing, the improved machine is preferably driven by a motor i the drive shaft of which is fitted with a grooved pulley 2 over which is trained. an end- 1A pinion 5 is fixed to the shaft of the driven pulley d and meshes with gear-wheel 5 keyed on a shaft i. Shaft 7 is supported at 9 with ball bearings 8. To the other end of shaft "I is clutched-in the Archimedes screw 62 by'means of a toothed clutch ll'. Ifhe screw l2 revolveswithin cylinder Id provided with a liner It and with a feeding 23, inclined in the opposite direction to the direction of said screw I2, as shown in detail in Figs. 2 and -3. Said grooves extend also within the hopper and have their beginning at 22.

In liner it, are cut helical grooves Inside cylinder it are also placed perforated platm I5. The end of the cylinder ll opens in a discharslnshead it provided with cavities I1 and 9. The mouth of cavity It opens on the paste, and during said operation, is pushed forward, with a gradually increasing pressure, to-

wards the group of perforated plates is.

' The mixture is seized by said screw this action being facilitated. by'the ribs 22 of the grooves ,in cylinder i3, and the progress of the paste during the kneading operation, is obtained through the rotation of the screw I72. The perforated dies iii form a resistance to the passage of the paste, so as to cause an increasing pres- Of course, the shape and the details of design may vary without thereby exceeding the limits of the present invention.

Having now-particularly described and ascer-. tained the nature of my said invention and in what manner the same is to be performed, I declare that what I claim is:

A continuous machine for the automatic productlon of macaroni including an elongated cylindrical casing, an upright inlet hopper at one end thereof, a discharge head at the other end of the casing, a die supporting ringat the outer end of the discharge head, an elongated screw of uniform cross section rotatably mounted in the bottom of the feed hopper and the major portion of the casing and terminating short of the other end of the casing, the interior of the cas-, ing housing the screw and the bottom of the feed hopper havingjuniform spiral grooves of a pitch opposite to that of the screw, and perfo rated plates arranged transversely of the casing
